What Causes the Volkswagen Coolant Temperature Gauge to Flash?

The flashing coolant temperature gauge indicates insufficient coolant level or excessive temperature. It is recommended to add some coolant and continue monitoring. If the gauge still flashes after adding coolant, the coolant temperature sensor should be checked. Below are the reasons for excessive car temperature: 1. Insufficient coolant: Leakage and reduction of coolant can cause the temperature to rise. In this case, check for any coolant leakage. If there is a leak, the leaking component should be repaired as soon as possible. If there is no leakage, the corresponding coolant should be added promptly. 2. Problem with the cooling fan: A faulty cooling fan can cause the temperature to rise. When the vehicle is running at high speeds, the generated heat cannot be transferred to the antifreeze in time, affecting heat dissipation and leading to an increase in antifreeze temperature, which may result in boiling over.
